| 简介 |
Provided is a method for manufacturing a metal powder by providing a reducing solution by dispersing caustic alkali, and hydrazine and/or hydrazine hydrate into a solvent; providing a metal salt solution comprising a salt of electroconductive metal, a rare earth metal salt and a solvent; and mixing the reducing solution with the metal salt solution to form a metal powder by depositing a hydroxide derived from the rare earth metal salt and by reducing the salt of electroconductive metal. With this metal powder manufacturing method, the sintering of the metal powder is restricted at a low temperature, the sintering initiation temperature is shifted to a higher level, and rapid sintering shrinkage is restricted, while ceramic grain growth is not accelerated. |
